Kalahari Eegion : Transvaal ; without precise locality, J. H. 

 McLea in Herb. Bolus. 



A woody perennial with erect, subtevete, striate, hispido-scabrid 

 branches. Leaves opposite, very shortly petioled, ovate or elliptic- 

 ovate, narrowed at the base, obtuse or subacute, rugose, crenate- 

 serrate, roughly hispidulous above, hispid on the nerves beneath, 

 gland-dotted, 3-5 cm. long, 1-1*5 cm. broad; petiole 2 mm. long. 

 Bracts broadly oblong, abruptly acuminate or caudate-acuminate, 

 truncate at the base, hispid on both surfaces and especially 

 along the margins, not exceeding the flowers, 3-4'5 mm. 

 long, 2-2-5 mm. broad. Calyx conspicuously 2-lobed, 4-nerved, 

 softly villous without, 1*5-2 mm. long; lobes almost as long as 

 the tube, 2-nerved, more or less obscurely 2-toothed. Corolla 

 villous above the middle externally, puberulous in the throat, 

 4-5 mm. long. 



L. pcdunculata has affinities both with L. scaberrima and 

 L. asperifolia, being apparently more closely allied with the former. 

 The most marked characters which separate it from L. scaberrima 

 are found in the 4-toothed calyx, the smaller bracts, the more 

 pronounced hairiness, and the comparatively smoother surface of 

 the whole plant. From L. asperifolia it differs in the 4-toothed 

 calyx, the larger bracts and spikes, and the less hairy, rougher, and 

 larger leaves. 



Gen. BOUCHEA, Cham. 



The following descriptions of three * new species of Bouchea and 

 an amended description of B. glandulifera invalidate the key to the 

 section Chascanum f to which all these species belong. For the 

 convenience of students using the Flora Capensis, a revised key for 

 that part of the genus is here given. J 



Section 2. Chascanum. Eipe fruit not separating spontaneously 

 into cocci ; areole basal or on the anterior face ; flowers bracteolate. 



Areole basal : 



Leaves toothed (6) cuneifolia. 



Leaves entire (7) latifolia. 



* B. incisa is at present known only from a locality within the tropics. It is, 

 however, included here, as it may confidently be expected to occur in extra-tropical 

 Transvaal.
